Analysis in k-space of Magnetization Dynamics Driven by Strong Terahertz Fields
Valentino Scalera, Matthias Hudl, Kumar Neeraj +4
Demagnetization in a thin film due to a terahertz pulse of magnetic field is investigated. Linearized LLG equation in the Fourier space to describe the magnetization dynamics is de…
Nonlinear magnetization dynamics driven by strong terahertz fields
Matthias Hudl, Massimiliano d'Aquino, Matteo Pancaldi +7
We present a comprehensive experimental and numerical study of magnetization dynamics triggered in a thin metallic film by single-cycle terahertz pulses of MV/m electric f…
Anti-reflection coating design for metallic terahertz meta-materials
M. Pancaldi, R. Freeman, M. Hudl +4
We demonstrate a silicon-based, single-layer anti-reflection coating that suppresses the reflectivity of metals at near-infrared frequencies, enabling optical probing of nano-scale…
THz-driven demagnetization with Perpendicular Magnetic Anisotropy: Towards ultrafast ballistic switching
Debanjan Polley, Matteo Pancaldi, Matthias Hudl +3
We study THz-driven spin dynamics in thin CoPt films with perpendicular magnetic anisotropy. Femtosecond magneto-optical Kerr effect measurements show that demagnetization amplitud…
Thermodynamics around the First-Order Ferromagnetic Phase Transition of Single Crystals
